¼ price is equals to %25 of the book price which mean the write option is B .
16² = 18² + 19² - 2(18)(19)cos(z)
256 = 324 + 361 - (684)cos(z)
256 = 685 - (684)cos(z)
-429 = -684cos(z)
cos(z) = -429/-684
z = cos⁻¹ (0.627)
z = cos⁻¹ (cos 51) [ Cos 51 = 0.627 ]
z = 51
In short, Your Answer would be: 51
Hope this helps!

Answer:
The total you have to pay for the TV is $115.9
Step-by-step explanation:
When we have a discount we have to make a substraction, when we have tax we have to sum so:
$125.67 * 15 % = 18.85
125.67 - 18.85 = 106.82
Now we have to add the tax
106.82 * 8.5% = 9.08
106.82 + 9.08 = 115.9
